My preferred form of these baffles is the specification, and particularly defined by shown in Figures 17 2, and 3. These con the claims terminating the same. sist of a series of round `or conical shells 2 ln the accompanying drawings, wherein which are vertically spaced one above the 75 l have shown my invention in certain forms other and which are spaced at their edges which are now preferred by me, Figure 1 is from the inner wall of the bucketrl. an elevation of my device showing it as it I prefer that all of these shells 2 except would appear in operation. v the lowermost shall have its central portion., Figure 2 is a section through my device. or its apex, cut away in order that portions 8o Figure 3 is a plan view. of the watermay passthrough the openings Figure 4 is a section of `a modified conthus remaining.

This is cen- 95 The strainer proper consists of a bucket trally positioned within the series and re- 1 of mesh material sufficiently line to retain ceives the greater volume of water as it flows y the smallest weed seeds. This is .provided from an upper ditch 3 into a lower ditch 30, with a suitable bottom 10 `of either mesh or and deflects the water outwardly into the solid material. The bucket is supportedv by various baffles 2. This should be sufciently 100 veniently, the ends of therodf -may .be

turned inward to torm the followers 23 which will slide in suitable guides, asthe channels 15. These channels are vertically positioned inside the bucket 1, and may bel placed ,opposite the frame members ll of vthe buckeuand will cooperate therewith to supportthe mesh ,1f and Atoikeep iit ,in proper upright pesition. A central `;ro d 2a mayalso ybe i .employed :to secure together ,the series of balileswQl andthe batllefZO, and this rod may extend downward ,to contact with thebottom lQofkthebucket andto support the series oi? baiiles at Athe. propenelevation within the bucket.

One orpmore intermediate baiiies oftruncated conical, shape,;as shown at27, may be secureduponthe `cone 25. to act` similarly to the intermediate ,baffles ot .the preferred form. VThis series of baiiles is supported uponarod'Qlt, and may be guidedin the channels 15 inany suitable manner, as vlby the` followers "28.

`My strainer is positioned within an irrigation system where there is a slight drop from a flume 3 to a ditch 30. `The fiume dischargesits contents into the Ycenter ofthe bucket and deflectors 20 and 2 direct the water outwardly against the mesh of the bucket with more or less force. The water passes through the mesh and as it runs down the outside of the bucket` is deflected outwardly and runs oit' at the edges of the collars 14. .The seeds and other dbris oontained in the water are washed down the inside of the. bucket and are deposited in its bottom.` At suitable intervals the series oi' baliies is removed and the bucket is emptied and then replaced. By this means all ofthe objectionable matter is removed from Vthe irrigation water and not distributed through the ditches.

Itwill be evident that a bucketor strainer of thistype might be 'found useful for other purposes than for removing seeds from an irrigation water. One use to which it might be put,.on account of the possibility of using line mesh material in its construction buckeaoutwardly through its walls.
